What is the mass of one mole of Iodine?
The number 115 is the mass number, so the mass is 115 amu. One amu (atomic mass unit) is about 1.66 x 10-27 kg, so if your looking for the mass of one atom of In-115, multiply 1.66 x 10-27 kg by 115. That's about 1.9 x 10-25 kg. You chemistry teacher should have taught you this, and probably did, if you were paying attention in class.
How many atoms are in 127 g of calcium?
The gram atomic mass of calcium is 40.08. Therefore, 127 g of calcium constitutes 127/40.08 or 3.69 gram atomic masses. By definition of Avogadro's Number, each gram atomic mass contains Avogadro's Number of atoms. Therefore, the answer is 3.69 X Avogadro's Number or 1.91 X 1024 atoms, to the justified number of significant digits.
Mass number of most common isotope of fluorine?
Almost all fluorine isotopes are Fluorine-19, which have 10 neutrons. Only trace amounts of Fluorine-18 can be found in nature.
Which element has an atomic number 127?
It is not necessary to name it, unless it has been published....
What is the weight of iodine?
gram-Equivalent of iodine is 127 because its molecular weight is 2(127) and 2 electron change involve in the redox titration
How neutrons are there in iodine?
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
How many neutrons are in Pb-210?
The "210" is the mass number. The mass number is the sum of the number of neutrons and the number of protons. So if you can locate a Periodic Table, you can see that lead's atomic number of 82, which means it has 82 protons. If you do a little subtraction (210-82), you can find the number of neutrons in this particular isotope, which is 128.
How many neutrons does iodine cost?
Iodine typically has an atomic number of 53, which means it has 53 protons. The most common isotope of iodine, iodine-127, has 74 neutrons. To find the number of neutrons in an isotope, you subtract the atomic number from the mass number; for iodine-127, that calculation is 127 (mass number) - 53 (atomic number) = 74 neutrons.
An atom of atomic number 53 and mass number 127 has how many neutrons?
because neutrons and electrons weight nearly the same, and electrons have such little mass that they are virtually insignifigant, the amount of neutrons can be found by subtracting the protons from the total weight. total weight-protons=neutrons(roughly) so in this case, the cobalt (atomic # 27) has 28 neutrons
How many neutrons are there in iodine?
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
What is the mass number of an atom of iodine with 76 nuetrons?
The mass number of an atom is determined by the number of neutrons and protons. Since you already know the number of neutrons, you just need the number of protons, then you can add them together. I happen to know that iodine has 53 protons, so that means that the mass number is 127.It is the protons and neutrons added together so when you add 53 and 74 you get 127! Hope that helped a lot!! :):):):):):):)
How do you find out how many neutrons are in iodine?
To find out how many neutrons are in any element, you must take the atomic mass of the element and subtract the atomic number/ the number of protons. # of neutrons = atomic mass - # of protons This is because the atomic mass of an element is the number of protons added to the number of neutrons. The atomic mass is measured in atomic mass units, where one proton has a mass of 1 amu and one neutron has a mass of 1 amu. Elements also have electrons, however their mass is negligible, which means that it can be ignored because it is minor. In the case of iodine, it's atomic mass is approximately 127 (126.9). It's atomic number, which is also the number of protons and the number of electrons, is 53. Thus, the number of neutrons is: 127 - 53 = 74
How many neutrons are in iodine-127.?
I-125 contains 73 neutrons. To calculate the number of protons, electrons, and neutrons in an uncharged isotope, follow these rules: Protons = atomic number Electrons = protons = atomic number Neutrons = atomic mass - protons Iodine is number 53 on the periodic table, so its atomic number is 53. It has 53 protons and 53 electrons. This particular isotope of iodine is I-125. So, it has 125-53=72 neutrons.
What is the atomic mass of and atom?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
The iodine isotope with 74 neutrons?
An isotope of iodine with 74 neutrons would have a mass number of 53 +74 = 127. Therefore its symbol would be I -127 or 127 C 53. 127 and 53 should be written as superscript and subscript respectively before writing the chemical symbol of iodine when using the later (127 C 53).Ê 53 is the atomic number of iodine.ÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊ
The atomic mass of iodine is less than the atomic mass of tellurium. but an iodine atom has one more proton than a tellurium atom. explain how this situation is possible?
The atomic mass of an element is determined by the total number of protons and neutrons in its nucleus. Iodine (atomic number 53) has more protons than tellurium (atomic number 52), but its atomic mass is lower because it has fewer neutrons. While iodine has 53 protons, it typically has 74 neutrons, giving it an atomic mass of about 127 amu, whereas tellurium has 52 protons and usually 76 neutrons, resulting in an atomic mass of about 128 amu. The different neutron counts in their isotopes lead to iodine having a lower atomic mass despite having more protons.
How many neutrons are in most atomic of iodine if the atomic number is 53 and the atomic weight is 126.9?
Most atomic of iodine has 74 neutrons. The atomic weight of iodine (126.9) represents the combined mass of protons, neutrons, and electrons in the atom. Since the atomic number (53) represents the number of protons in the nucleus, subtracting the atomic number from the atomic weight gives the number of neutrons.
